Hi grc

I would respectfully have to disagree. Thinking of the shoulders as a ""conduit" through which energy is transferred" can be misleading. Energy for the swing does not travel like an electrical current. If that were so, energy would transfer through the shoulders whether they rotated or not. --- That was the point of the question. Energy for the swing can't jump like lightening from the hips (or whatever) to the bat. Far to many coaches leave the importance of shoulder rotation out of their teaching.
